Important Fund Information
The Global Total Return and Global Dynamic Income Funds may invest up to 100% of their assets in foreign securities and invest in an array of security types and market-cap sizes, each of which has a unique risk profile. As a result of political or economic instability in foreign countries, there can be special risks associated with investing in foreign securities. These include fluctuations in currency exchange rates, increased price volatility, and difficulty obtaining information.

Investments by the Funds in lower-rated securities involve substantial risk of loss and present greater risks than investments in higher-rated securities, including less liquidity and increased price sensitivity to changing interest rates and to a deteriorating economic environment.

There are certain risks associated with an investment in a convertible bond such as default risk--that the company issuing a convertible security may be unable to repay principal and interest--and interest rate risk--that the convertible may decrease in value if interest rates increase.

Fixed-income securities are subject to interest rate risk; as interest rates go up, the value of the debt securities in the Fund's portfolio generally will decline.

Global Total Return and Global Dynamic Income Funds may invest in derivative securities. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. There is no assurance that any derivative strategy used by the Funds will succeed. One of the risks associated with purchasing an option is that the Funds pay a premium whether or not an option is exercised.

Shares of closed-end funds frequently trade at a market price that is below their net asset value.

Leverage creates risks which may adversely affect return, including the likelihood of greater volatility of net asset value and market price of common shares; and fluctuations in dividend rates on any preferred shares.
